GRANTS PASS, Ore. (AP) – Most of the large wildfires burning east of the Cascade Range in Oregon for the past two weeks are at or near containment, but a new round of intense lightning storms is forecast this week.

The Northwest Interagency Coordination Center in Portland reported Monday that six of 11 large wildfires now range from 80% contained to fully contained.

The Buzzard Complex is the largest wildfire in the nation and is 98% contained after burning 618 square miles of rangeland about 45 miles southeast of Burns.

Isolated lightning is forecast Monday and Tuesday in southern Oregon, particularly east of the Cascades. Lightning storms are expected to become more intense Wednesday through Sunday from central Oregon to the Idaho border, with moderate to heavy potential for starting large fires.
